Nuclear power Definition and 116 Threads

Hi everyone, i am student at nuclear engineering. So i have a questions about the future of nuclear power. After Fukushima disaster, many country have reviewed about nuclear power, and like Germany, they are going to close the nuclear power reactor. So can you tell me about the future of nuclear...

Looks like the glory days of nuclear power is over. https://www.youtube.com/watch?v=DG3Z5e9rfW0 http://www.usatoday.com/news/world/2011-05-30-germany-nuclear-power_n.htm http://www.reuters.com/article/2011/05/30/us-germany-nuclear-idUSTRE74Q2P120110530 Don’t know if this is a good or...

I read that nuclear power when used for propulsion of a vehicle can be very efficient for example nuclear powered submarines and aircraft carriers can run over twenty years without refueling and can travel enormously long distances with the fission of a few kilograms of uranium,but why is this...

After reading news of the Japan nuclear power plant, I have some questions: (1) If the fuel rod heats up on their own to the point of melting, how were they created to begin with, and how were they transported, or stored? (2) What is the source of the fuel rods? If the radioactive...

Hi, I needed to know some things about reactivity and how it is changed by different factors while making a reactor critical? Control Rods, Booster Rods, Boron, Moderator Level, Xenon etc are affecting the reactivity of the reactor, but how to find out their contribution at certain point and...

How to calculate for any nuclear power plant 1. Thermal efficiency 2. power plant load factor 3. availability factor 4. capacity factor 5. core power density 6. specific power 7. linear power density 8. fissile loading 9. fuel enrichment 10. fuel burn-up 11. fuel residence time

A couple questions. 1: Does US have anything similar to KHG? US robots on site in Fukushima - one with digital radiation monitor, other looking at first through camera - is that what US would use at US reactor accident? Is there a shortage / unavailability of such equipment for US-built reactors...

Tell the world about the horrible site engineering the Fukushima crisis has exposed. The Low Tsunami protection in a major earthquake zone with a wall that was notdesigned to protect the plant in a worst case scenario. They have a recorded history of high tsunamis in the past yet they...

Could one really big hydrogen fuel cell battery replace a nuclear reactor in providing power to millions of people? This may end up being a safer option for generating power.

I had been planning for awhile to study nuclear engineering at the undergraduate level and eventually do graduate work and enter the field. Now, with what happened recently, I mean is the field shot? I really find this stuff interesting and am wondering if the field still has a good future...

I'm posting this in the Politics & World Affairs folder. Stress on World Affairs; not politics.Carbon energy sources will peak in 2017, 2030 or one hundred years from now. Probable closer to the first than the last. This will put a strain on the demand for the life styles to which we have...

Decay rate help I've been debating decay rates with another poster in another forum. Basically, the other poster has stated "The half-life/decay rate of the substances used in nuclear power generation have nothing to do with the generation of power. That they ARE radioactive is. Spent fuel...

I've reposted this in the nuclear engineering forum, which seems more appropriate. I'd just delete it, but can't see the way to do so. I've been debating decay rates with another poster in another forum. Basically, the other poster has stated "The half-life/decay rate of the substances...

Power plants are among the first targets in a war, and a nuclear reactor blast by a weapon would release its radioactivity accumulated in normal use just as an accident like Chernobyl does. A country with many reactors transformed into dirty bombs would be uninhabitable. Unfortunately...

Hi All: My question is, why do some nuclear power plants have cooling towers and some don't? Why spend extra money on cooling towers if the feedwater can be cooled by the large body of water such as lake? Thanks!

questiion guys.. why nuclear power uses diff kind of elements such as plutonium? while sun has only two elements two produce energy. i ask that question because i am curious on how energy is created trough atom fusion. while studying the basic principle of chemical reaction of the SUN...

What do Cape Wind and nuclear power have in common? Opponents come out of the woodwork to oppose both and there is no regulatory framework in place to limit the challenges for either. As a result, opponents can litigate the projects into oblivion. Case in point, Cape Wind. It is currently...

This article, http://www.counterpunch.com/stclair03122010.html Sadly for the credibility of the atom lobby, some of their more eye-grabbing numbers don't check out. For example, as noted in a report by the Nuclear Energy Institute, the nuclear industry claims that the world's 447 nuclear...

Obama has issued loan guarantees to build two new nuke plants. Anyone know what kind of plants they will build? Are we really going to finally restart the American nuclear industry?

If a 1 GW nuclear power plant runs continuously for 18 months, determine the mass of U 235 consumed by the plant, assuming an average fission energy yield of 202 MeV. Any help would be appreciated.

In the midst of the debate about the price of oil, constantly we hear the reference to nuclear power as a solution. This is a fallacious argument that I have probably heard referenced at least 50 times, here, and in the news media. As is evident from McCain's suggestion of a 300 million...

Hey, Quite an interesting topic and I've been bits and bats on the internet, but what do you think is the main links or what are your views?

what is the difference between emergency diesel generators and station blackout disel generator? Is Station blackout disel generator just a redundant sysyetm for emergency disel generators?

I think this might be an easy one but I am stucked right now and would really appreciate some help. How much mas is produced under a year by a nuclear power plant that gives 1,0 GW. Edit: ok seems like i made the newbie mistake to post this in the wrong forum, please forgive me moderator...

Hi there nuclear lovers! Myself lives in sweden, and here it is illegal to do research in nuclear power (experimental), and to build new reactors, research in new fissible nuclides and so on. And also barley no money is invested in the reactors we do have, so they are not in good shape...

Australia is going to move to nuclear power over the next decade. I would like to work in this area but don't have a degree. I have a particular interest in physics and have done a year of university maths/physics befor giving up. At the time I was getting average scores and had no prospect of...

Hi, I was wondering if anyone could give me a simple description on what nuclear power is. I.e. how the neutrons from UO2/U/PuO2 are harnessed for power? Also, if anyone knows any useful links for information on nuclear power, different types of ractors etc, then it will be very useful :smile:

I live in Saskatchewan, which has the world's largest and richest Uranium mines (producing 35% of the world's uranium from deposits as rich as 25%). But at present rates of extraction, the known reserves will last only 20 to 30 years according to the Cameco, the largest uranium producer. It...

I had heard about a nulcear reactor, that did not require a critical mass, and therefore did not have the possibility of Loss of coolant or meltdown. a reactor that required power to run, so if you want you can "Switch it off". seems the present day reactors create a critcal mass, and all...

Hi Does anyone know where I can get some in depth info on the various forms of nuclear waste i.e the actual elements/isotopes, how they decay and their half lives etc. I'm in the process of writing my part of a group project (lucky me I got the nuclear waste bit !:cry: ) and although I can...

I want to learn the GFD lead acid batteries used in NPP. Have Exide and Deka ever supplied for NPP, or who are the main suppliers in this field? We know VRLA betteried dominate the market now, but have this type ever been use in NPP? As for UPS, do bettery suppliers provide UPS together...

One of the main arguments that greens use against nuclear power is the waste factor, and how we have no real solution to this problem I was wondering what your take on the situation is? how long is it safe for waste to stay in Spent Fuel Pool, and am I right in saying it is then transferred...

New Nuclear Power Generation in the US Announced! I posted about this in the Nuclear Engineering Forum, but this may signal the "Nuclear Rennaisance" in the US, so I'm repeating here for discussions on energy policy rather than technology...

What safety systems are there to prevent a LOCA?? (Loss Of coolant Accident) I've googled but nothing has surfaced that relates to LOCA.

I have recently become interested with the return of Nuclear Engineering with the recent political climate change over our dependence on foreign energy resorces. I know that there is another thread which discusses the prospects of new plants in detail, however I wanted to look at the long range...

I've always thought that a small nuclear reactor installation that would power an average size county (as opposed to a large city county) would be more efficient that the large installations such as Three Mile Island. Less expensive to construct and operate. Anyone care to comment on...

Ok, I am giving a talk on nuclear power at the weekend, and a few questions have popped up that I am unsure about. 1. Why do we get nuclear waste exactly? 2. Why would we want to use a pebble shape for future fission reactors? 3. What issues are there with decommissioning of plants? 4. Why...

Is it the case that every country in the world--including places like North Korea, Iran and Syria--ought to have the right to build nuclear power plants? (That is, the question is not whether such countries currently have a legal right under international law.) A. Yes B. No
